Abstract

Cables covered with polyethylene used for cable-stayed bridges have high anti-corrosion performance, but it is difficult to grasp the condition of the internal wires when the polyethylene is damaged. Therefore, temperature and humidity inside the cable and steel pipe measured in order to clarify the behavior of temperature and humidity that is affected the cable corrosion when the polyethylene was damaged. As the result, it was clarified the difference in humidity behavior between steel pipe and cable, and grasped the trend of temperature and humidity inside the cable.
